Only if you have more than one number. If you have 2 numbers then you can route them to the correct location based on the number called.
If you are talking about having a single line with a single number which you want to use for both voice and fax then 3CX cannot discern between the different types.
The SPA 3102 may be able to discern between the different types but i don't know if it can route to multiple destinations, a read of the manual would hopefully tell you.
